In this physics worksheet, students develop an understanding of the atomic model and how atoms relate to one another through answering the seven questions.

In this physics worksheet, high schoolers examine the theory of quantum mechanics through the answering of the nine questions. The answers are accessed through the links by each question.

Students define, identify and illustrate the parts of an atom, and investigate the Bohr atomic model. Students watch a multimedia presentation to understand an atom's parts and their functions. In groups, they create a model of an atom...

Students study the significance of the quantum model and how scientific theories adapt over time.  In this investigative lesson students describe the contributions that scientists have helped develop the atomic theory and identify...

Eighth graders view a PowerPoint presentation that assist them in distinguishing between physical and chemical changes. They compare their observations of demonstrations to a list of clues recognizing types of changes.

Trace the sequential process of the developing theories of atomic structure in the early 20th century, show, in historical development, how scientists "know" things, how experiments are set up and how interpretations are drawn from them,...

Students identify how to relate the position of an element in the periodic table to its atomic number and atomic mass. They identify how to use the periodic table to identify metals, semimetals, nonmetals, and halogens, and also,...

Students investigate what is wrong with the Rutherford atomic model. In this chemistry lesson, students answer questions about the atomic model after watching a video. They draw conclusions from the video and discuss how the atomic model...

Students explain that the Standard Model of the atom includes particles beyond protons, neutrons, and electrons. They describe the nucleus as conglomeration of quarks that manifest themselves as protons and neutrons.

Students examine the electromagnetic spectrum and demonstrate the elements within.  In this investigative lesson students complete a demonstration and calculate the energy of a photon. 

Students explore scientific discovery while watching a video. They, in groups, are to research a scientific invention and present their findings to the class.
